This is where we will post our past weekly math problems! We post a problem every week around Saturday at noon. We will only have weeks starting at Week 31 of 2022. Click the button for the archive of the rest of the problems.

For every level Kevin completes in his favorite game, he earns 520 points. Kevin already has 200 points in the game and wants to end up with at least 2580 points before he goes to bed. What is the minimum amount of levels Kevin needs to complete to reach his goal?

To solve this, we can set up an equation where x is the amount of levels Kevin needs to complete.

200 + 520x = 2580 where 200 is the starting point and 2580 is the amount of points Kevin wants to finish by the end of the night.

*x*⋅520+200≥2580

*x*⋅520≥2580−200

*x*⋅520≥2380

The minimum amount of levels Kevin needs to complete is 520.

Kevin sells magazine subscriptions and earns $4 for every new subscriber he signs up. Kevin also earns a $33 weekly bonus regardless of how many magazine subscriptions he sells. **If Kevin wants to earn at least **$36** this week, what is the minimum number of subscriptions he needs to sell?**

Since the Amount earned this week =

Subscriptions sold × Price per subscription + Weekly bonus, we can set up an inequality to determine how many we need. Amount sold this week should be equal or greater than 36 which means Subscriptions sold x price per subscription + weekly bonus ≥ 36. We can now plug in: *x*⋅$4+$33≥$36*x*⋅$4≥$36−$33*x*⋅$4≥$3*x*≥34≈0.75 Since Kevin cannot sell parts of subscriptions, we round 0.75 up to 1. **Kevin must sell at least 1 subscriptions this week.**

Divide x3−12x2−42*x*3−12*x*2−42 by x−3*x*−3

Divide x^3+x^2+x+1 by x+9

See image.

Final answer: x^2 - 8x + 73 - (-656/x+9)
